as Glaims. (01. 140-113) This invention relates to machines for making wired boxes and box parts and particularly'to machines for forming and perpetuating U-shaped bights on the ends of wires secured to box parts.

It is an object of the invention to provide certain improvements in the type of machine disclosed in my Patent No. 1,933,031 of October 31. 1933, whereby the wired box parts to be operated upon may be automatically fed into and through the machine.

It is a further object to provide an automatic feed for a machine of the type referred to which is controlled by the box parts in their movement to and through the machine.

It is a further object of the invention to provide a machine of the type referred to with an automatic control to correlate the operation of the machine with the operation of a box blank machine which staples the binding wire to the box parts.

. It is a further object of the invention to provide a machine of the type referred to with an automatic feed and a control therefor of such character that a succession of wired box partsleaving a box blank machine will be automatically fed into and through the bight-forming machine.

Other objects will be in part obvious and in part pointed out hereinafter.

' controls a bight-forming operation after such an operation has been completed and the box parts are again moving through the machine.

In Fig. 1 is shown one illustrative product of the machine, namely, a wired box blank consist- 30 ing of four sections of cleats A and side material B connected together in foldable relationship by wires C which extend across and are stapled to the several sections. Each end of each wire C is bent to form a U-shaped bight D, the two bights thus formed being adapted to interengagewith each other to close the box when the several sections of the box blank are folded into box form.

In Fig. 2 is shown a crate blank. This blank is similar to that shown in Fig. 1 except that the side material B of the several sections consists of spaced slats.

In Fig. 3 is shown a box end consisting of a sheet B of veneer, resawed lumber or fibreboard, and wires 0 stapled thereto and provided at their ends with bights D. I

In the manufacture of the products shown in Figs. 1, 2 and 3, the wires C are stapled to the box parts in what is commonly known as a box blank machine. A typical box blank. machine is shown in U. S. Patent No. 1,738,806 of December 10, 1929, reference to which is hereby made for a detailed description of such a machine.

In the box blank machine the box parts, i. e., the cleats A and the side material B in the case 56 of the blanks shown in Figs. i and 2, are positioned on endless conveyor chains and fed be neath staple forming and driving mechanism which staples the binding wires C to the side material and the cleats A. When box ends such as the end shown in Fig. 3 are being made, a succession of sheets B are positioned on endless conveyor chains and fed beneath the staple forming and driving mechanism which staples the wires C thereto.

.In the box blank machine such as that disclosed in said U. S. Patent No. 1,738,806 the conveyor chains are advanced continuously at substantially. a uniform speed and the staple forming and driving mechanism is constructed and arranged to operate upon the moving box parts.

In placing the box parts on the endless conveyors of the box blank machine adequate spaces are left between units of work, i. e., box blanks or box ends as the case may be, to provide sufficient lengths of wire between each unit to be severed and formed into bights to provide the bights D as shown in Figs. 1 to 3. Thus a succession of wire-connected box blanks or box ends are delivered continuously from the delivery end .of the box blank machine with appropriate lengths of wire therebetween to permit severing the wires and forming and perpetuating a bight on each severed end.

Heretofore the wire-connected box blanks emerging from the box blank machine were manually fed into 'a bight'forming machine of the type shown in said Patent No. 1,933,031. When in correct position to be operated upon in the bight-forming machine, the machine was manually thrown into operation to sever the wires, form prongs on the severed ends, swing the prongs over onto their respective box parts to form bights and drive the prongs through the box parts to perpetuate the bights. After this operation the bight-forming operation automatically stopped and the finished box blank was manually pulled through and removed from the bightforming machine. This manual feeding of the box blanks to the bight-forming machine and the manual removal of the finished blanks required two attendants for the bight-forming machine.

The present invention is intended to eliminate the necessity for these two attendants by providing an automatic feed for the box blanks to, through and out of the bight-forming machine.

Because the wired box blanks emerge from the illustrative box blank machine continuously and at substantially .a uniform speed, and because the bight-forming mechanism of the illustrative bight-forming machine does not operate upon moving work, the present invention includes an automatic control for the automatic feed of the work and an automatic control for the operation of the bight-forming mechanism, both controls being operated in accordance with the relationship of the box parts to the bightforming machine and mechanism, all of which will now be described.

Referring to Flgs. 4 and 5. the box blank machine which staples the binding wires to the .box parts is generally indicated by the reference numeral l, and the bight-forming machine which I t. In the absence of mechanism to feed the wired box parts through the bight-forining machine they would of course fall to the ground. Mechanism is provided in the bight-forming machine to pull the wired box parts up onto a curved guide I and onto a table T mounted to reciprocate vertically in the bight-forming machine at the proper time, as described in'said Patent No. 1,933,031 to present the wires to, the operation of the bight-forming and perpetuating mechanism.

The mechanism for pulling the wired box parts into and through the bight-forming machine consists of a pair of moving belts 5 which engage the sides of the wired box parts and feed them through the bight-forming machine.

As the work-feeding means of the illustrative box blank machine continuously deliversa succession of wire-connected box parts and as the illustrative bight-forming mechanism operates only when the box parts are at rest, it is necessary to interrupt the movement of the feed belts 5 at intervals to permit the bight-forming mech-} anism to operate, and it isalso necessary to so regulate the intermittent feed of the belts 5 with the continuous feed of the conveyor chains 3 of the box blank machine i that the bight-forming machine will handle, the output of the box blank machine without interrupting the operation of the latter. This is accomplished by running the belts 5 of the bight-forming machine at a higher rate of speed than that at which the chains 3 of the box blank machine are moved, and by providing an automatic control for the belts 5 which operates to stop and start the belts 5 in accordance with the output of the box blank machine.

As the wire-connected box blanks leave the box blank machine 3 they'pass beneath a clutch control arm 6 carrying a large roller 60 which rides upon the wire-connected box parts. The box parts then ride up on the guides 4 into the bight-forming machine through the action of the belts 5 which frictionally engage the sides of the wired box parts.

As best shown in Fig. 7 belts 5 are .rotated about pulleys l and la. Pulleys I are keyed to shafts 9 journaled in frames 8, and pulleys la are rotatably mounted on shafts 9a secured to frames 8,. Shafts 9 are rotated in a mannerpresently to be described.

Frames 8 are adjustably secured to the table T and may be adjusted sidewise on table T to accommodate box parts of various widths.

Still referring ttiFig'i- '7, the belts 5 are held against the sides of the box parts by rollers Ill and Illa. Rolle'rs 10 are mounted in castings ll secured to frame 8. Rollers 'lla are held against belts 5 by springs 12' interposed between castings Na and the belts 5. Castings Ila are adjustably mounted on frames 8 to regulate the spring tension against the belts 5;

The belts 5 may be recessed about rollers l3 to provide clearance for the wire-serving and bightforming devices} I when box blanks of the type shown in Figs. 1 and 2 are being operated upon. When, however, box ends of the type shown in Fig. 3 are being operated upon the belts 5 need not be recessed and maybe run straight as shown in dotted lines in-Fig. '7.

As the'wired box Darts pass-through the nightforming machine they are supported by stock supports-l5 adjustably secured to'the table 'I' and areheld from vertical movement by presser bars it which are carried by rods l1.

As shownin- Figs. 6 and 8, the belts s are driven by a motor which is continuous in operation. A pulley 42 secured to the drive shaft of motor 43 is connected by a belt with a pulley 39 which is mounted on a shaft 4 Pulley 39 is driven continuously by motor 43, but because belts 5 must be driven intermittently, pulley 39.

is clutched to shaft 46 by a clutch 6 only at those selected times when the belts 5 are to be be driven.

, 6| are held in mesh by a bracket 62.

The feed belts 5 arestarted and stopped in the following manner:

When the wired box parts generally designated E in Figs. 1 and 2 sag between the box blank machine and the bight-forming machine and permit control arm 6 to move to the low position shown in dotted lines in Fig. 5, clutch l3 will be operated as hereinafter described to clutch pulley 39 to shaft 46 to cause rotation of pulleys 1 to drive the belts 5. Since the belts 5 move faster than conveyor chains 3 of the box blank machine, they will soon remove'the sag in the box parts between the two machines and raise the box parts and the control arm 5 to the position shown in full lines in Fig. 5. This movement of the control arm 6 to the full line position in Fig. 5 disengages clutch It in the manner hereinafter described and stops movement of the belts 5.

As shown in Fig. 8, the raising of clutch control arm 6 rocks in a counter-clockwise direction a shaft l9 journaled in brackets 36 secured to machine frame 31. Secured to shaft I9 is a crank 20 pivotally connected to a link 2|. The other end of link 2| (see Figs. 10 and 11) has a pin and slot connection'with a crank 22 pivoted at 23 in a casting 14. The other end of the crank 22 engages a clutch collar 24 which engages and disengages clutch l6.

The raising of control arm 5 moves link 2| to the left in Fig. 8 and through crank 22 moves clutch collar 24 to release position.

A spring 13 connecting clutch collar 24 with casting 14 holds the clutch collar free of the clutch face when the clutch is engaged and also holds crank 22 in position to be operated by link 2|.

After the clutch I! has been disengaged by the raising of control arm 6, belts 5 remain stationary until the wire-connected box parts between the two machines sag to. the position shown in dotted lines in Fig. 5, whereupon clutch II will again be engaged through the action oil-link 2| and crank 22 to cause the belts 6 to starts feeding movement.

Preferably, there is sumclent'free movement of clutch collar 24 to permit considerable movement of link 2| before the clutch is released or engaged so that the clutch will not be released until vvcontrol arm 6 reaches the raised position shown chine and so that the bight-forming machine will handle the output of the box blank machine without interrupting-the operation of the latter. Because movement of the box parts through the bight-forming machine must be interrupted for each bight-forming operation, asecond automatic control for the-feed belts 5 is] providedto interrupt the'feed of the belts 5 when each box part is in correct position to be operated upon by the bight-forming mechanism.

As shown in Fig. 8, the forward edge of each wired box part comes in contact with a stop link 32 having a downwardly projecting nose 33. Stop link 32 is pivotally mounted on a crank 34 secured to a rock shaft35 mounted in the brackets 36 secured to thedrame 31. The movement of the box part against nose 33 of the link 32 moves the link to the left in Fig. 8, thus rocking shaft 35 in a clockwise direction.

As shown in Fig. 7,, shaft 35 carries at its right hand end a crank 38 connected to a link 3| the other end of which has a pin and slot connection withcrank 22 which operates clutch collar 24. Thus when the forward edge of each box part contacts the nose 33 of link 32 and rocks shaft 35, clutch l8 will be disengaged and the feed of belts 5 will stop. The arrangement is such that the belts 5 are stopped when the forward edge of the box part is in correct position to be operated upon.

The rocking of shaft 35 to discontinue the feed ,of belts 5 also throws into operation the bightforming mechanism for one cycle of operation and a. gear 8| connected to shaft 54, the chain v 6|! passing over the gears 18 and 8|. When shaft 35 isrocked to stop movement of the feed belts 5 a crank 44 which is secured to shaft 35 engages and moves a fork 45 secured to a vertical shaft 46 and rocks shaft 46. As best shown in Fig. 13, the rocking ofshaft 46 releases a catch 41 and permits a loaded compression spring 48 to rock a shaft 49 mounted in brackets 49a secured to a base frame 31a.

As shown in Figs. 7 and 10, vrotary movement of shaft 49 acting through a link 50a, a bell crank 56b, a link 50c, and a lever 56d, moves the yoke of a clutch collar 56 on vertical shaft 68 to partially engage clutch 53 to connect shaft 19 to motor shaft 63. This same rotary movement of shaft 49 acting through link 50a, bell crank 56b, link 530, a link We, a bell crank 56], and a link 66a, throws a buffer arm 5| from theposition shown in Fig. 8 to the position shown in Fig. 9 to permit a one-cycle cam 52 to be released and to allow shaft 54 to be rotated by chain 66 as shaft 19 is rotated.

Partial engagement of clutch 53 as just explained causes initial rotation of shaft 54 and cam 52. As shaft 54 starts turning, the surface of cam 52 cont-acts a lobe 55 on buffer arm 5| and moves the buffer 5| to the left as shown in Figs. 9 and 12. This movement is transmitted through link 50g, bell crank 56,f, link Sue, and lever 50d to clutch collar 56 which is further shifted to engage completely clutch 53,- as shown in Fig. 10.

When clutch 53 is engaged as Just explained. the bight-forming mechanism is thrown into operation for one complete cycle to perform the bight-forming operations described in said Patent No. 1,933,031. During a bight-forming operation table T is raised and lowered as described in said patent.

As the table T is lowered a cam 53 which is secured to it contacts crank 22 and keeps it from moving until table T rises. As heretofore stated, crank 22 controls the action of clutch it which operates the feed belts 5 and when held in this position by the cam 53 the clutch l3 will be disengaged during a fastener supplying operation. Thus it is assured that the clutch i3 which operates the feed belts 5 will remain disengaged while a fastener supplying operation is taking place.

- The lowering of the table T also sets a device which will automatically disengage the clutch 53 when the fastener supplying operation is completed, as now described.

Secured to the table T is a piston 15 and a frame 55 both of which rise and fall with the table T. Mounted on frame 54 to pivot vertically is a cam 55 which is normally held inthe position shown in Fig. 8 by a spring 55 and an abutment (not shown) on the frame 5| so that the cam is free to move upward but not downward from the position shown inFig. 8. As the table T falls the cam 55 is pivoted upward about its pivot point by an arm 51 mounted on an extension of shaft 58 upon which the yoke of clutch collar 55 is mounted. When cam 55 passes below arm 51, it snaps in under the'arm 51. It remains in this position until table T starts to rise when the fastener supplying operation has been completed. The cam 55 rises with the table and contacts arm 51. Cam 55 and arm 51 are so formed as to move arm 51 out of the path of travel of the cam and this movement of arm 51 causes shaft 55 to be rockedand thereby shift clutch collar 55 to disengage clutch 53 and stop the operation of the bight-forming mechanism. Cam 55 and arm 51 are so shaped and positioned that disengagement of the clutch 53 will not be completed until the table T is in raised position. This rotation of shaft 58 through the action of the linkage hereinbefore described causes bufler 5| to be returned to initial position and thus prevent overrunning of shaft 54.

The rotation of shaft 53 is transmitted through the linkage hereinbefore described to shaft 43 which it rotates counterclockwise (Figs. 7 and 8) This rotation of shaft 43 reloads compression spring 48 and reengages catch 41, the release for catch 41 having been returned to initial position as now described.

As the table T falls, stock stop 32 is held from falling by an arm Ill extending from a bar H which is secured to a cross bar 12 (see Fig. 8). As the box blank E moves downward with table T from the position shown in Fig. 9 to that shown in Fig. 12, stock stop 32 is held above the box blank by the arm 10. The removal of the box blank E from contact with nose 33 of stock stop 32 allows the stock stop 32 to be pulled back to the position shown in Fig. 12 by a spring 59 which has been put in tension by the action of the box blank against the stock stop 32. The release of stock stop 32 allows spring 59 to rock shaft and pull the stock stop 32 to the position shown in Fig. 12. This rotation of shaft 35 causes crank 45, fork l5 and shaft to be returned to initial position, thus returning the release for catch 41 into engaging position.

When the table T rises (Fig. 14) nose 33 of stop 32 rests on the stock E. It is prevented from being inadvertently tripped by a knob 51 which rests against bar II and prevents the stop 32 from being moved forward until it drops into a clear space between box blanks.

The stock stop 32 is adjustable in length by means of a screw 53 to accommodate various lengths of fasteners with which boxes are to be equipped. The nose 33 of the stop 32 is narrow so that it will flt between the wire C and the belts 5 without interference.

The operation of the machine is as follows:

The box parts E are placed on the continuously moving conveyors 3 of the box blank machine I. They are fed through the box blank machine which staples the binding wires to the box parts. The wired box parts on leaving the blank ma; chine pass beneath clutch control arm '5 and onto guides 4 into the fastener supplying machine 2. The box parts are drawn from the blank machine and into and through the fastener supplying machine by the moving belts 5. Belts 5 are thrown into operation when clutch control arm 5 reachesthe lowered position, i. e.,

-when there is an accumulation of box parts between the machines I and 2. Since the belts 5 move faster than conveyors 3 the belts take up these accumulated box parts and draw the wires taut, thus raising clutch control arm 5. When the arm 5 is raised to the position shown in full lines in Fig. 5, clutch I8 is disengaged and feed belts 5 are thrown out of operation. When more box parts have been accumulated between the machines i and 2 the control arm 5 falls and reengages the clutch l3 to throw the feed belts 5 into operation.

The movement of the belts 5 will be stopped as each box part trips stock stop 32. This tripping action causes clutch l3 to be disengaged when the box part is in position to be operated upon. This action also trips the latch 51 which starts the fastener supplying mechanism. .When a fastener supplying operation is completed its operation is automatically stopped through the action of the one-cycle clutch.

The clutch l8 which controls the operation of the belts 5 is kept disengaged by the action of cam surface 53 against arm 22 during a fastener supplying operation.

When thefastener supplying operation is completed clutch I3 is again engaged through the action of control arm 5 to cause feed belts 5 to move the completed box parts out of the fastener supplying machine and to move additional box parts into the machine to be operated upon.

Among other advantages this invention pro vides a high speed mass production machine for wiring box parts and providing them with interengageable fastening means. An attendant places the box parts on the conveyors 3 of the blank machine and the completed product is delivered by the feed belts 5 of the fastener supplying machine, the box parts in their movement into and through the fastener supplying machine automatically controlling its operation.

The words continuous and continuously as used in the claims to define the feed movement of the box parts to the binding wire applying mechanism are intended to define a feed movement in which the box parts are moving at the time the binding wire applying mechanism is operating thereon as distinguished from a feed movement in which the box parts are moved intermittently between operations of the binding wire applying mechanismand are at rest when said mechanism is operating thereon.

It will be understood that the invention is not to be limited to the specific embodiment shown for purposes of illustration as it may be variously embodied without departing from the invention.

It will also be understood that all of the features of the invention need not be used conjointly as they may be used to advantage in various combinations and subcombinations as deflned by mt sub-Joined claims.
